Could an example of energy sink be described as "Earthing" of electrical cables, where excess electricity is channeled to the earth to dissipate? In this example, the earth is the sink?

Today, we make use of various sources of energy found on earth to produce electricity. Using machines, we convert the energies of wind, biomass, fossil fuels, water, heat trapped in the earth (geothermal), nuclear and solar energy into usable electricity.

Can we use the power of the sun which is none destructive in the long term but actually helps the world

please give us examples of energy sinks.. i can not think of any practical examples. the only possible sink is Fukushima.. plant is still producing energy, but it is all being lost and not utilised as with the Chernobyl… the uranium cores are still active and live..

There are many sorces of energy, which at the present time. The energy sources that is environmetally friendly are from wind, solar, water thermal etc. However, they cost too much of money. So, from my idea, incinerator that uses petrol still necessary.

I would like to ask one question. My question is how to convert the geothermal into electricity?

Diploma in Environmental Science - Energy Sources and Sinks

The source of energy for many processes occurring on the earth\'s surface comes from the sun. Radiating solar energy heats the earth unevenly, creating air movements in the atmosphere. Therefore, the sun drives the winds, ocean currents and the water cycle.
Sunlight energy is used by plants to create chemical energy through a process called photosynthesis, and this supports the life and growth of plants. In addition, dead plant material decays, and over millions of years is converted into fossil fuels (oil, coal, etc.).
Today, we make use of various sources of energy found on earth to produce electricity. Using machines, we convert the energies of wind, biomass, fossil fuels, water, heat trapped in the earth (geothermal), nuclear and solar energy into usable electricity.
Sources of energy differ in amount, availability, time required for their formation and usefulness. For example, the energy released by one gram of uranium during nuclear fission is much larger than that produced during the combustion of an equal mass of coal.
An energy sink is anything that collects a significant quantity of energy that is either lost or not considered transferable in the system under study. Sources and sinks have to be included in an energy budget when accounting for the energy flowing into and out of a system.
